Tensors (also known as multidimensional arrays or N-way arrays) are
used in a variety of applications ranging from chemometrics to
psychometrics. The Tensor Toolbox provides the following classes for manipulating dense, sparse, and structured tensors using MATLAB's
object-oriented features:
- tensor - A (dense) multidimensional array
(extends MATLAB's current capabilities).
- sptensor - A sparse multidimensional array.
- tenmat - Store a tensor as a matrix, with extra information so
that it can be converted back into a tensor.
- sptenmat - Store a sptensor as sparse matrix in
coordinate format, with extra information so
that it can be converted back into a sptensor.
- ttensor - Store a tensor decomposed as a Tucker operator
(see below).
- ktensor - Store a tensor decomposed as a Kruskal operator
(see below).
For more details about what tensors are, see the
Glossary.
What's New in Version 2.2?
Version 2.2 adds some new functions for tensor and sptensor and fixes
bugs in the tensor and sptensor classes. To see a complete
list of changes, view the RELEASE_NOTES.txt file.
